Struct EdgeAssertion 

pub struct EdgeAssertion {
    pub source: String,
    pub target: String,
    pub edge_type: String,
    pub valid_from: String,
    pub valid_to: String,
    pub weight: f64,
    pub properties: String,
}

Edge assertion builder for assert / retire / re-assert lifecycle operations.

Fields

source: String

target: String

edge_type: String

valid_from: String

valid_to: String

weight: f64

properties: String

Implementations

impl EdgeAssertion

pub fn new( source: impl Into<String>, target: impl Into<String>, edge_type: impl Into<String>, ) -> Self

pub fn valid_from(self, ts: impl Into<String>) -> Self

When the asserted fact starts being true (valid time, Doctrine II).

pub fn valid_to(self, ts: impl Into<String>) -> Self

When the asserted fact stops being true. Defaults to the open sentinel.

pub fn weight(self, weight: f64) -> Self

pub fn properties(self, json: impl Into<String>) -> Self

pub fn normalized(self) -> Result<Self>

Check the assertion and put its timestamps in canonical form (D-029).

Runs before the write reaches the actor, so a malformed edge type or a second-precision timestamp comes back as a typed error rather than as an engine CHECK failure from the other side of a channel — by which point the caller has lost the context that would explain it.

Trait Implementations
